2022 Porsche Taycan Electrical System Problems

I am reporting a safety defect involving (1) sudden loss of propulsion (“turtle mode”/limp mode) while accelerating/merging into traffic and (2) unintended steering movement while driver-assist/lane centering was active (vehicle jerked toward adjacent lane and off roadway). These events create an immediate crash risk. The vehicle has also had repeated charging-related overheating/charging stoppage events, which I believe may present a fire risk when charging in a residential garage. Repairs have been attempted multiple times by an authorized Porsche dealer, but defects persist. Warranty has now expired, and an independent scan shows ongoing network/data bus/12V monitoring faults consistent with continuing electrical/network instability. I am requesting NHTSA review for a potential safety defect investigation/recall.

This incident is related to the ARB7/24V-732 recall, first communicated to me in November, 2024 and again in July, 2025. The July, 2025 letter states that software would be installed in the vehicle to test the health of my vehicle's battery, at a Porsche Center. I believe that this was actually performed over-the-air at my home. It's my guess that because the software was installed over-the-air, the normal process to close out a recall did not occur. I did not receive notification that my vehicle was determined to be healthy, and it isn't clear when NHTSA did. The slow or non-reporting of the vehicle recall status has had a ripple effect, as practically every third party tracker of recall information believes that the recall is still active on my vehicle. This is impacting the vehicle's worth in the market and may be impacting insurance rates and other vehicle health-dependent service costs. Porsche claims that it is my responsibility to correct the record of the vehicle with third parties, when it is their negligence that is causing the work. I see this as unfinished work on their side, and I ask NHTSA to help drive Porsche Cars North America to complete their work. Moreover, Porsche should be compelled to notify all customers whose health check was performed remotely that their vehicle was found to be healthy and that the recall was lifted on their vehicle. Lastly if it is not mandated that the OEM is responsible to communicate the resolution of recalls performed without service receipts, then this should be considered alongside any other updates to law. Thanks for any help that you can provide.

While waiting for light to turn green atba highway off raml, the car dash displayed two errors in quick succession and would not move. The errors were "Engine control error Park vehicle in a safe place" and "Electrical system error Restarting not possible, Service required". There was also an error about PSM, but I wasn't able to get a picture of it. I turned the car off and back on, which did not resolve the error. I then turned the car off, got out of the car, locked it, and got back in and turned it back on and it drove normally. This has happened twice.

On April 14, 2025, I suffered an electric shock injury while using the Porsche Mobile Charger Plus (Part No. 9J1.971.675.AC; Model PMCPU96A) that came with my 2022 Porsche Taycan, purchased as a Certified Pre-Owned (CPO) vehicle on April 5, 2025, from Braman Porsche in Florida. The injury required emergency medical care and hospitalization. I continue to experience symptoms and am undergoing physical therapy and cardiology follow-up. After the incident, I learned that multiple NHTSA safety recalls and technical bulletins (e.g., 23V-841, APB6, ARB5, ARB7) were already active at the time of sale, affecting both the vehicle and charger. These bulletins cite overheating and internal defects that may cause safety hazards during charging. Despite the vehicle being sold under the Porsche CPO program, no recall was disclosed to me at the time of purchase. The dealership later returned a different charger than the one originally supplied, but I retained the original unit that caused the shock. I am preserving it for potential forensic examination. I am filing this complaint to request that NHTSA investigate the Porsche Mobile Charger Plus and the dealership’s sale of vehicles with open safety recalls. This appears to be a serious and ongoing risk to consumer safety.

NHTSA campaign 24V732000 is a recall of 27,000 Porsche Taycans for high-voltage batteries may short circuit and increase risk of fire. For vehicles in Porsche campaign ARB6 for which online data is unavailable, owners are advised to have the recalled vehicles inspected and limit charging to 80%. In December 3, 2024, letter (attached) to UK Taycan owners of Taycans in ARB6, in addition to limiting charge to 80%, Porsche writes: “Additionally, until the inspection has been completed, we would advise not to charge the vehicle under cover and or to ensure the vehicle is not parked adjacent to or under buildings.” Why is Porsche’s warning to UK Taycan owners in ARB6 not to charge their Taycans under cover and ensure the vehicle not parked adjacent to buildings not included in the ARB6 notification letter to US Taycan owners?

Beginning around 45,000 miles, my 2022 Porsche Taycan began experiencing recurring failures in the surround view/backup camera system. One or more camera views will appear blank with a crossed-out camera icon. This affects the federally mandated rear backup camera as well as other viewing angles. The issue occurs intermittently but has become more frequent. The vehicle is available for inspection upon request. This defect puts my safety and others at risk by eliminating rear visibility when reversing, increasing the likelihood of hitting pedestrians (especially children), missing low obstacles, or colliding with vehicles in blind spots. Backup cameras are critical for preventing these incidents, particularly in driveways, parking lots, and tight urban spaces. The problem has been confirmed by Porsche Silver Spring in Maryland during a recall visit. They stated the repair is not covered and quoted approximately $20,000 to replace the system. The cameras are original equipment and have not been tampered with. The vehicle has not been inspected by police or insurance representatives, but the defect has been documented in photographs. There were no warning lamps prior to the first failure—only the blank camera screen and crossed-out icon when the failure occurs. Other Porsche Taycan owners have reported similar issues, suggesting this may be a broader design or component defect. I request NHTSA’s investigation to determine if this is a widespread safety defect requiring a recall or manufacturer-supported repair program.

The Porsche EV Charger started an electrical fire in the wall of my garage while charging on May 21st 2024. The charger melted as a result. On the way to take my car to the dealership the dash became very hot to the touch as well. Fast forward to today, my car is still at the dealership. They have contacted me and asked me to pick it up and return my loaner car. They cannot however provide me with a new charger for my car. Porsche has sent out new chargers as part of this recall but they don't have the software in place so the chargers are useless right now. Porsche will give $500 toward the purchase of a 3rd party charger but they told me that they will not accept any responsibility if the third party charger damages my vehicle in any way and they acknowledge that using the suggested 3rd party charger may void my vehicle warranty. They refuse to provide me with a loaner car until my car can safely be charged with a Porsche charger that wouldn't void my current warranty.

What component or system failed or malfunctioned, and is it available for inspection upon request? Electrical malfunction errors came on, brakes, and engine control warning lights came on. The speedometer dashboard went dark. The car started shaking. The car started to slow down on its own. How was your safety or the safety of others put at risk? I was traveling at 76mph on a six lane highway. The brakes were not responsive for a period of time, I had no way to see the car speed, the windows went down on their own in the back seats. It was 33 degrees outside, no heat in the car, the wireless phone charger stopped working. Has the problem been reproduced or confirmed by a dealer or independent service center? The car is being inspected by the dealership. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? It is being inspected today. Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? Yes, the brake warning light came on, an electrical malfunction light, and an engine control light appeared

The 240V charger cable has a recall due to overheating and causing fires. I am now having to charge my car with a slower cable. In addition, I have also heard that the battery can have issues with water and leakage causing fires as well. I am concerned with fires by charging the car in my home, and the fact that this car was sold to me, and the charger cable has been known to have issues for years, only now getting a recall letter in Feb 2024.

Sudden loss of power while on freeway with several errors being thrown onto driver's screen. Unable to accelerate. Was forced to coast to shoulder of road and come to a complete stop. Turned off vehicle and turned on again and issue was resolved.

The heater and defrost are not working which is especially dangerous during cold weather and/or humid conditions. The vehicle is at the dealership service center where they stated there have been a number of similar issues. The dealer has indicated they will inspect and repair. There were no warning lamps/messages prior to failure. To be fair, I never tried the heater before a cold spell this last week.

I received a red error stating that there was an electrical system error and I couldn’t operate my vehicle on Oct 18 when the vehicle was parked at home. I had to tow the vehicle to the dealer and when they inspected it, they couldn’t find anything wrong with it. I brought the vehicle back home and then less than a month later on November 7 I got the same error when the vehicle was parked at home. I had to tow the vehicle again to the dealer. And at this time they told me that there is an issue with the high voltage battery. They have not given me a loaner, and I am without a vehicle. I do not know when the issue will be resolved.

In September 2023 this Porsche Taycan 4S accelerated suddenly while going very slowly in reverse after displaying a red warning message on the dashboard "Electrical System Error." The brakes did not work and the car crashed into a house. No one was injured, but the car was declared a total loss. I see a recent safety recall (April 19) on your website for issues with the lithium battery and I believe that this may have caused my accident. I did report this as a safety issue to you in 2023 and confirmed tracking number assigned by NHTSA for this issue is 11556555.

Electrical System Failure and Engine Failure. Car just stopped in the middle of the road at the traffic light and would not move forward. This has happened for the second time since the purchase of the car in December 2022. The car is now at the dealer being checked.

Electric passenger compartment heater (high-voltage heater) Does not work. This prevents the cabin from receiving heat. This is extremely unsafe in cold environments because it prevents the windshield visibility as frost forms.

On 3/26/23 my 2022 Porsche Taycan Turbo self-ignited in our garage and created a lithium fire literally incinerating itself and completely destroying 3 other cars, the garage and approximately 35% of our home. The resulting fire filled the home with smoke, soot and required us to leave the house immediately and we have yet to return. The car was not being charged at the time of the fire; the charging unit was stored in the truck anticipating the dealership's promise to pick up the car for repair (again) the very next day. It was a four alarm fire supervised by the Bloomfield Township Fire Department and Oakland County Sheriff's Department. My wife and daughter personally witnessed the origin of the fire. The flames came from the bottom of the driver's side wrapping over the top of the Porsche and igniting the garage and the other cars. All cars were a complete loss. The Porsche Taycan was originally purchased new on 9/30/22 and was in and out of the dealership starting 2/9/23. The Service History is attached herein.

After 9 days the car showing 12V battery low, it completely was completely dead on March 01, 2023 despite my all efforts to drive around (more than 400 miles) and charging. Reported the issue to Porsche helpline and they arranged the vehicle pickup from my home same day and the car was serviced at Paul Miller Porsche dealership in Parsippany, NJ. They charged the 12V battery, updated the software and returned after 3 days. The big battery had around 35% charge when it happened. Luckily it happened at home but I’m nervous about taking it out and get stranded somewhere.

The heating system in my 2022 Porsche Taycan stopped working. In addition to it not being able to heat the cabin, I can't defog/defrost the windshield making the car unsafe to drive. I'm told by the Porsche dealer that this is a known issue, and the fix involves ordering a part from Germany with unknown ETA.

I was driving at high speed on the freeway when, suddenly and without warning, the vehicle lost all power. A message reading “Electrical System Error Park Vehicle in a Safe Place”. I was able to glide across five lanes in rush hour traffic to the breakdown lane.

High voltage heater unit stopped working. Unable to defog front windshield leading to dangerous loss of visibility, in addition to unable to heat cabin. I see LOTS of similar reports online. At dealer, awaiting part which will take weeks.
